EAST BOSTON, Mass. - Sunlit Ridge, a homebred owned by Manfred Roos, is the undisputed leader of New England's 3-year-old filly turf division and also the best Massachusetts-bred sophomore of any gender. On Saturday, she will take on open older fillies and mares in the $25,000 Highland Happening Stakes. The 1 1/16-mile turf race attracted an overflow field of 14, including several shippers, but only 10 will run.
